For the last several years I have had Firefox configured to display all website fonts in my custom font, Dyslexie. As of upgrading to v119 yesterday, I have lost this function; all websites now display their native fonts. I still have Firefox Settings Default Font set to Dyslexie, but it no longer works. Any help would be appreciated.

To include user installed fonts: layout.css.font-visibility => 3

Fingerprinting protection overrides that setting (3 is the default) unless privacy.fingerprintingProtection.overrides is set to -FontVisibilityBaseSystem,-FontVisibilityLangPack in about:config.
